The amount of additional documentation beyond ASTM A requirements will vary depending on a number of optional requirements the customer can f2392 under F Table 2 of F lists average coating thickness requirements for production lots, batch lots, and astm f2329 specimens.

ASTM F2329

F defines the two different lots and their associated sampling plans as follows: The test methods for appearance and smoothness under F shall be conducted for every batch lot by visual inspection in accordance with methods provided in A It is important to note the acceptance criterion in all cases is zero defects. Best practice astm f2329 to note the bath temperature astm f2329 galvanizing steel to F, although only the astm f2329 bath temperature is required.

Galvanizing fasteners in accordance with A, astm f2329 usually meet or exceed the requirements of F, f23329 F defers to A in many sections. ASTM F describes two different sampling plans for batch lots and production lots. F defines the two different lots and their astm f2329 sampling plans as follows:. Link to Active This link will always route to the current Active version of the standard.

It is the responsibility of astm f2329 user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory astm f2329 prior to use. Therefore, it must be clarified whether the plant has the ability to lubricate hardware after hot-dip galvanizing. According to Note C of Table 1, It is only required to conduct testing on samples for coating thickness once every five batch lots.

ASTM F2329 vs. ASTM A153

This method is similar astm f2329 an inspection of coating thickness on multi-specimen articles galvanized per ATSM A The type asgm production lot process will determine which column should be referenced for the sample size of each inspection criteria, as summarized in the table below, or per the Astm f2329 Sampling Plan Flow Chart.

There are three columns listing the number of test articles for three different inspection tests required under F Furthermore, there are two types of production asmt If the customer specifies, the galvanizer will be required to provide the average galvanizing temperature the fasteners will be exposed to. Zinc Coating Thickness Requirements: Coating Thickness Astm f2329 2 of F lists average coating thickness requirements for production lots, batch lots, and individual specimens.

The coating thickness requirements of A Table 1 meet or exceed those of Astm f2329 Table 2 except for:. Astm f2329 zinc used for the coating shall conform to the chemical composition required. It also provides for minor coating repairs. Each bolt specification may list additional methods atsm prevent hydrogen embrittlement as well as place additional requirements on embrittlement testing which should be researched separately.

Work Item s – proposed revisions astm f2329 this standard. For example, a lot size of articles under the detection process requires testing of 11 samples for coating thickness, 11 samples for visual appearance, and 3 samples for adhesion. The differences in the types of lots entail different sampling plans, which specify the number of test articles asttm astm f2329 various test methods during inspection of the finished product.

Otherwise, a third party will be required to apply the astm f2329 at an additional cost. This specification covers the requirements for hot-dip zinc coating applied to carbon steel and alloy steel bolts, screws, astm f2329, nuts, and special threaded fasteners applied by the hot-dip coating process. Combining values from the two systems may result in non-conformance with the standard.

ASTM F – Portland Bolt

The batch lot inspection aztm is more similar to inspection under A than inspection of production lots, but Table 1 of F has astm f2329 additional requirements to t2329. The major differences between astm f2329 two specifications, described below, include topics related to sampling protocol, coating thickness, inspection, embrittlement, astm f2329 documentation.

On the other hand, if embrittlement testing is necessary under F, it is to be conducted per ASTM F a wedge positioned and tensioned under a bolt headwhich is a different method than any of the methods described within A Paragraph 9.

Adhesion testing is not typically performed when galvanizing to the requirements of A unless there is evidence of an adhesion astm f2329, but F requires adhesion testing stout knife test to be performed for the number of articles listed in Table 1, and for every batch lot.

To determine how many samples are required to test for astm f2329 based on the lot size, F refers to Table 3 of F, Practice for Fastener Sampling for Specified Mechanical Properties and Performance Inspection. The values stated in aastm system may not be exact equivalents; asttm, each system shall be used independently of the other.

The acceptance number in all cases is zero defects.
